The Bafang BBSHD motor, combined with a 42t Lekkie chainring & the standard 34/22 10sp cassette Surly Wednesday cassette, is more than ample power for difficult trails. Even at lower speeds the power is there when needed. Programming the motor (1-9 settings), allows you to control just how much power you want or need for the riding situation.
The present programming for the motor has the motor speed limits set from 10% - 75%.
With the bicycle gearing setup, less than 30% of the motor speed is normally needed for most trails.
